1. A spring suspension for vehicles com an auxiliary spring carried between the'ends of the ,lever and pivotally connected to the end of the main spring.

3. In a spring suspension for vehicles, a main spr ng, a lever pivoted atone end to a relatively fixed support, a clampingv yoke at the other endgof the lever mova ly engaging the spring I inside its end, an auxil- 'iary spring supported on the lever between "at one end thereof to said sup ably'engaging said spring a istance inside the end of the latter, an auxiliary spring supported on said lever at its pivot end and "a plunger connected to said spring and pivtween its en s with a ringthe ends of the latter and a plunger connectedto the auxiliary spring and pivoted to the end of the main spring. v

4; In a" spring suspension 101'? vehicles, a main spring provided at one end with an eye, a support for the spring, a lever pivoted rtpand movoted to said eye of the main spr ng.

" 5. In a spring suspension forvehicles, a main spring, a lever pivoted at one end thereof. to a relatively fixed support, a clamping yoke carried'by the other end of the lever, the arms of which engage over the sides of said springwith a cross pin connecting the ends Of'said arms whereby the a lever may be removably attached to the a main s ring, an auxiliary spring supported on the ever at its pivot end and a plunger connected. to the auxiliary spring and pivoted to the end of the main 5 ring.

6. In a spring suspension or vehicles, a main spring, a lever pivoted at one end to a relatively fixed support, a clamping yoke at the other-end of the lever movably en agingthe sprin said lever being rovide bei e frame, a casing supported on the ring-like frame a plunger slidable in the casing and provided at one end" with a head, a spring between the head and the lower end of the casin and means to connect the plunger to the en of the main spring;
